2022-12-16hw/intc/xics: Reset TYPE_ICS objects with device_cold_reset()Peter Maydell2-8/+1
The realize method for the TYPE_ICS class uses qemu_register_reset() to register a reset handler, as a workaround for the fact that currently objects which directly inherit from TYPE_DEVICE don't get automatically reset. However, the reset function directly calls ics_reset(), which is the function that implements the legacy reset method. This means that only the parent class's data gets reset, and a subclass which also needs to handle reset, like TYPE_PHB3_MSI, has to register its own reset function. Make the TYPE_ICS reset function call device_cold_reset() instead: this will handle reset for both the parent class and the subclass, and will work whether the classes are using legacy reset or 3-phase reset. This allows us to remove the reset function that the subclass currently has to set up.

Convert the TYPE_CXL_ROOT_PORT and TYPE_PNV_PHB_ROOT_PORT classes to 3-phase reset, so they don't need to use the deprecated device_class_set_parent_reset() function any more. We have to do both in the same commit, because they keep the parent_reset field in their common parent class's class struct.

Convert the child classes TYPE_PS2_KBD_DEVICE and TYPE_PS2_MOUSE_DEVICE to the 3-phase reset system. This allows us to stop using the old device_class_set_parent_reset() function. We don't need to register an 'exit' phase function for the subclasses, because they have no work to do in that phase. Passing NULL to resettable_class_set_parent_phases() will result in the parent class method being called for that phase, so we don't need to register a function purely to chain to the parent 'exit' phase function.

2022-12-16Replace use of qdev_reset_all() with device_cold_reset()Peter Maydell5-5/+5
The legacy function qdev_reset_all() performs a recursive reset, starting from a qdev. However, it does not permit any of the devices in the tree to use three-phase reset, because device reset goes through the device_legacy_reset() function that only calls the single DeviceClass::reset method. Switch to using the device_cold_reset() function instead. This also performs a recursive reset, where first the children are reset and then finally the parent, but it uses the new (...in 2020...) Resettable mechanism, which supports both the old style single-reset method and also the new 3-phase reset handling. This commit changes the five remaining uses of this function.

2022-12-16hw/s390x/s390-pci-inst.c: Use device_cold_reset() to reset PCI devicesPeter Maydell1-1/+1
The semantic difference between the deprecated device_legacy_reset() function and the newer device_cold_reset() function is that the new function resets both the device itself and any qbuses it owns, whereas the legacy function resets just the device itself and nothing else. In s390-pci-inst.c we use device_legacy_reset() to reset an S390PCIBusDevice. This device doesn't have any child qbuses, so the functions do the same thing and we can stop using the deprecated one.

2022-12-15hw/misc: Move some arm-related files from specific_ss into softmmu_ssThomas Huth3-8/+6
The header target/arm/kvm-consts.h checks CONFIG_KVM which is marked as poisoned in common code, so the files that include this header have to be added to specific_ss and recompiled for each, qemu-system-arm and qemu-system-aarch64. However, since the kvm headers are only optionally used in kvm-constants.h for some sanity checks, we can additionally check the NEED_CPU_H macro first to avoid the poisoned CONFIG_KVM macro, so kvm-constants.h can also be used from "common" files (without the sanity checks - which should be OK since they are still done from other target-specific files instead). This way, and by adjusting some other include statements in the related files here and there, we can move some files from specific_ss into softmmu_ss, so that they only need to be compiled once during the build process.

2022-12-15s390x/pci: reset ISM passthrough devices on shutdown and system resetMatthew Rosato2-0/+30
ISM device firmware stores unique state information that can can cause a wholesale unmap of the associated IOMMU (e.g. when we get a termination signal for QEMU) to trigger firmware errors because firmware believes we are attempting to invalidate entries that are still in-use by the guest OS (when in fact that guest is in the process of being terminated or rebooted). To alleviate this, register both a shutdown notifier (for unexpected termination cases e.g. virsh destroy) as well as a reset callback (for cases like guest OS reboot). For each of these scenarios, trigger PCI device reset; this is enough to indicate to firmware that the IOMMU is no longer in-use by the guest OS, making it safe to invalidate any associated IOMMU entries.

2022-12-15s390x/pci: shrink DMA aperture to be bound by vfio DMA limitMatthew Rosato1-0/+11
Currently, s390x-pci performs accounting against the vfio DMA limit and triggers the guest to clean up mappings when the limit is reached. Let's go a step further and also limit the size of the supported DMA aperture reported to the guest based upon the initial vfio DMA limit reported for the container (if less than than the size reported by the firmware/host zPCI layer). This avoids processing sections of the guest DMA table during global refresh that, for common use cases, will never be used anway, and makes exhausting the vfio DMA limit due to mismatch between guest aperture size and host limit far less likely and more indicitive of an error.

To fix it, we can change it to write these values to the dtb using a type width matching #address-cells. This is the intended size for these dtb properties, and is how u-boot, for instance, writes them, although in practice the Linux kernel will cope with them being any width as long as they're big enough to fit the value.

2022-12-15hw/intc/arm_gicv3: Fix GICD_TYPER ITLinesNumber advertisementLuke Starrett1-2/+2
The ARM GICv3 TRM describes that the ITLinesNumber field of GICD_TYPER register: "indicates the maximum SPI INTID that the GIC implementation supports" As SPI #0 is absolute IRQ #32, the max SPI INTID should have accounted for the internal 16x SGI's and 16x PPI's. However, the original GICv3 model subtracted off the SGI/PPI. Cosmetically this can be seen at OS boot (Linux) showing 32 shy of what should be there, i.e.: [ 0.000000] GICv3: 224 SPIs implemented Though in hw/arm/virt.c, the machine is configured for 256 SPI's. ARM virt machine likely doesn't have a problem with this because the upper 32 IRQ's don't actually have anything meaningful wired. But, this does become a functional issue on a custom use case which wants to make use of these IRQ's. Additionally, boot code (i.e. TF-A) will only init up to the number (blocks of 32) that it believes to actually be there.

2022-12-15hw/arm/virt: Add properties to disable high memory regionsGavin Shan1-2/+73
The 3 high memory regions are usually enabled by default, but they may be not used. For example, VIRT_HIGH_GIC_REDIST2 isn't needed by GICv2. This leads to waste in the PA space. Add properties ("highmem-redists", "highmem-ecam", "highmem-mmio") to allow users selectively disable them if needed. After that, the high memory region for GICv3 or GICv4 redistributor can be disabled by user, the number of maximal supported CPUs needs to be calculated based on 'vms->highmem_redists'. The follow-up error message is also improved to indicate if the high memory region for GICv3 and GICv4 has been enabled or not.

2022-12-15hw/arm/virt: Add 'compact-highmem' propertyGavin Shan1-0/+32
After the improvement to high memory region address assignment is applied, the memory layout can be changed, introducing possible migration breakage. For example, VIRT_HIGH_PCIE_MMIO memory region is disabled or enabled when the optimization is applied or not, with the following configuration. The configuration is only achievable by modifying the source code until more properties are added to allow users selectively disable those high memory regions. pa_bits = 40; vms->highmem_redists = false; vms->highmem_ecam = false; vms->highmem_mmio = true; # qemu-system-aarch64 -accel kvm -cpu host \ -machine virt-7.2,compact-highmem={on, off} \ -m 4G,maxmem=511G -monitor stdio Region compact-highmem=off compact-highmem=on ---------------------------------------------------------------- MEM [1GB 512GB] [1GB 512GB] HIGH_GIC_REDISTS2 [512GB 512GB+64MB] [disabled] HIGH_PCIE_ECAM [512GB+256MB 512GB+512MB] [disabled] HIGH_PCIE_MMIO [disabled] [512GB 1TB] In order to keep backwords compatibility, we need to disable the optimization on machine, which is virt-7.1 or ealier than it. It means the optimization is enabled by default from virt-7.2. Besides, 'compact-highmem' property is added so that the optimization can be explicitly enabled or disabled on all machine types by users.

2022-12-15hw/arm/virt: Improve high memory region address assignmentGavin Shan1-5/+10
There are three high memory regions, which are VIRT_HIGH_REDIST2, VIRT_HIGH_PCIE_ECAM and VIRT_HIGH_PCIE_MMIO. Their base addresses are floating on highest RAM address. However, they can be disabled in several cases. (1) One specific high memory region is likely to be disabled by code by toggling vms->highmem_{redists, ecam, mmio}. (2) VIRT_HIGH_PCIE_ECAM region is disabled on machine, which is 'virt-2.12' or ealier than it. (3) VIRT_HIGH_PCIE_ECAM region is disabled when firmware is loaded on 32-bits system. (4) One specific high memory region is disabled when it breaks the PA space limit. The current implementation of virt_set_{memmap, high_memmap}() isn't optimized because the high memory region's PA space is always reserved, regardless of whatever the actual state in the corresponding vms->highmem_{redists, ecam, mmio} flag. In the code, 'base' and 'vms->highest_gpa' are always increased for case (1), (2) and (3). It's unnecessary since the assigned PA space for the disabled high memory region won't be used afterwards. Improve the address assignment for those three high memory region by skipping the address assignment for one specific high memory region if it has been disabled in case (1), (2) and (3). The memory layout may be changed after the improvement is applied, which leads to potential migration breakage. So 'vms->highmem_compact' is added to control if the improvement should be applied. For now, 'vms->highmem_compact' is set to false, meaning that we don't have memory layout change until it becomes configurable through property 'compact-highmem' in next patch.
